RESUMO

OBJECTIVE: Subclinical atherosclerosis (SA) is often observed in ankylosing spondylitis (AS) patients; Salusin-α (Sal-α), Salusin-ß (Sal-ß), and Klotho hormones are thought to be associated with atherosclerosis. This study aims to evaluate the relationship between Sal-α, Sal-ß, and Klotho levels with SA in AS. PATIENTS AND METHODS: The study included patients older than 18 years who applied between August 1, 2019, and September 1, 2019. Patients with AS were included in the AS group, and patients without a known disease were included in the healthy group. Epicardial adipose tissue thickness (EATT) and carotid intima-media thickness (CIMT) measurements were used to assess SA. RESULTS: The study group included 38 (40.9%) patients diagnosed with AS, and the control group included 55 (59.1%) participants. CIMT and EATT levels were higher in the AS group than in the healthy group [0.37 (0.17) vs. 0.54±0.18, p<0.001; 0.44±0.11 vs. 0.54 (0.18), p=0.004, respectively]. There was no significant difference in Sal-α, Sal-ß, and Klotho levels between the AS and healthy groups (p>0.05). Furthermore, there was no observed relationship between EATT or CIMT and Klotho, Sal-α, or Sal-ß in either group (p>0.05). CONCLUSIONS: Although SA level was higher in AS patients, there was no relationship between SA and Sal-α, Sal-ß, and Klotho levels.

RESUMO

Many patients at increased risk of fractures do not take their medication appropriately, resulting in a substantial decrease in the benefits of drug therapy. Improving medication adherence is urgently needed but remains laborious, given the numerous and multidimensional reasons for non-adherence, suggesting the need for measurement-guided, multifactorial and individualized solutions. INTRODUCTION: Poor adherence to medications is a major challenge in the treatment of osteoporosis. This paper aimed to provide an overview of the consequences, determinants and potential solutions to poor adherence and persistence to osteoporosis medication. METHODS: A working group was organized by the European Society on Clinical and Economic Aspects of Osteoporosis, Osteoarthritis and Musculoskeletal diseases (ESCEO) to review consequences, determinants and potential solutions to adherence and to make recommendations for practice and further research. A systematic literature review and a face-to-face experts meeting were undertaken. RESULTS: Medication non-adherence is associated with increased risk of fractures, leading to a substantial decrease in the clinical and economic benefits of drug therapy. Reasons for non-adherence are numerous and multidimensional for each patient, depending on the interplay of multiple factors, suggesting the need for multifactorial and individualized solutions. Few interventions have been shown to improve adherence or persistence to osteoporosis treatment. Promising actions include patient education with counselling, adherence monitoring with feedback and dose simplification including flexible dosing regimen. Recommendations for practice and further research were also provided. To adequately manage adherence, it is important to (1) understand the problem (initiation, implementation and/or persistence), (2) to measure adherence and (3) to identify the reason of non-adherence and fix it. CONCLUSION: These recommendations are intended for clinicians to manage adherence of their patients and to researchers and policy makers to design, facilitate and appropriately use adherence interventions.

RESUMO

BACKGROUND: Tumor-associated trypsin inhibitor (TATI) is expressed with trypsinogen in tumors. We studied the clinical-pathologic association and significance of preoperative serum levels of TATI in gastric cancer patients. PATIENTS AND METHODS: Pre-treatment serum levels of TATI in patients with gastric cancer and healthy controls were analyzed by a specific enzyme-linked immunosorbent assay (ELISA). RESULTS: Statistically significant differences were found in serum TATI levels between patients with gastric cancer and healthy controls (p < 0.0001). There was a significant relationship between the serum levels of TATI and clinicopathological parameters. However, serum levels of TATI were significantly higher in patients with an advanced T stage (T3) (p < 0.001), lymph node metastasis (p < 0.001) and an advanced TNM stage (stage III or IV; p < 0.001). CONCLUSIONS: Our study suggests that TATI may be used to identify potentially high-risk groups of upper gastric carcinoma. Elevated level of TATI was associated with progressive disease or advanced stage.

RESUMO

OBJECTIVE: Biological levels of localized colon tumors are needed for the diagnosis and prevention of colon cancer. Numerous biomarker studies are produced currently through research. We investigated some peptides with the aim of identifying biomarkers for colorectal cancer and lymphatic and hepatic metastasis. MATERIALS AND METHODS: A total of 100 patients with histologically proven colorectal cancer and 60 normal volunteers were included in this study. Preoperative serum was collected for analysis. Human neutrophil peptides levels (HNP) were assayed by solid phase RIA (Radio Immun Assay) based on monoclonal antibodies. RESULTS: The HNP-1, -2 and -3-also known as α-defensin-1, -2 and -3-are present in elevated concentrations in the plasma from colorectal cancer patients. CONCLUSION: Preoperative high plasma HNP 1-3 levels are associated with colorectal cancer. The HNP 1-3 levels may procure information on patients with lymph node or hepatic metastasis.

RESUMO

UNLABELLED: The incidence of hip fractures in Turkey increased markedly from that reported in 1988/1989 so that FRAX® models for Turkey should be revised. INTRODUCTION: The MEDOS study in 1988/1989 reported that men and women from Turkey had exceptionally low rates of hip fracture. The aim of the FRACTURK study was to estimate current and future hip fracture risks and the prevalence of osteoporosis in Turkey. METHODS: Hip fracture cases in 2009 were identified from interviews of a population-based sample of 26,424 residents aged 50 years or more in 12 different regions of Turkey and in two hospital surveys. Bone mineral density was evaluated by DXA in an age-stratified sample of 1,965 men and women. RESULTS: Hip fracture incidence in the community-based survey was similar to that in the hospital survey. The age-specific incidence in men and women was substantially higher than that reported for 1988/1989. At the age of 50 years, the remaining lifetime probability of a hip fracture was 3.5% in men and 14.6% in women. In 2009, there were approximately 24,000 hip fractures estimated in Turkey, 73% of which were found in women. Assuming no change in the age- and sex-specific incidence, the number of hip fractures was expected to increase to nearly 64,000 in 2035. The prevalence of osteoporosis at the femoral neck was 7.5% and 33.3% in men and women, respectively, aged 50 years or more. CONCLUSION: Although Turkey is still among the countries with low hip fracture rates in Europe, the incidence has increased markedly in the last 20 years. This finding can be used to recalibrate fracture risk assessment models for Turkey.

RESUMO

BACKGROUND: Acute-phase response proteins (APRPs), cytokines, and hormones have been claimed to be an independent, important factor of cancers. We suggest that in gastrointestinal system cancers, changes in APRP, cytokines, and hormones are associated. METHODS: C-reactive protein (CRP), albumin, interleukin 1α (IL-1α), IL-1ß, IL-6, IL-8, IL-10, tumor necrosis factor α (TNF-α), midkine, vascular endothelial growth factor-A(VEGF-A), VEGF-C, VEGF receptor 1 (VEGFR1), leptin, adiponectin, and ghrelin serum levels are studied in 148 gastrointestinal system cancer types and 40 healthy controls. RESULTS: We found statistically significant differences and correlations between groups. We found significantly higher serum CRP, IL-1α, IL-1ß, IL-6, IL-8, IL-10, TNF-α, VEGF-A, VEGF-C, VEGFR1, and leptin concentrations in patients with esophageal, gastric, pancreas, colon, and rectum cancers than controls (p < 0.001, p < 0.0001). But, we found lower levels of the serum albumin, midkine, adiponectin, and ghrelin in patients with esophageal, gastric, pancreas, colon, and rectum cancers compared to control subjects (p < 0.05, p < 0.001). CONCLUSIONS: Cachexia in gastrointestinal system cancer types is associated with changes in APRP, cytokines, and hormone concentrations. This may be reflected between the outcomes in malignancies and the biomarkers.

RESUMO

Thymidine kinase (TK) plays an essential role in the processing of thymidine within the cell and therefore it is an important marker of proliferation, particularly in tumor cells. The aim of our study was to determine the diagnostic and prognostic importance of TK measurement in gastric adenocarcinoma. The serum level of TK was measured in 72 patients with gastric adenocarcinoma. Serum levels of TK were significantly elevated in gastric adenocarcinoma in comparison with healthy individuals. Also, we have found that there are significant variations in TK serum concentrations when measured that correlate with important variations in clinico-pathological features and prognostic significance (Tab. 2, Ref. 16).

RESUMO

The total des-gamma-carboxyprothrombin (DCP) produced in pancreatic adenocarcinoma and the correlation between the tissue DCP and serum DCP levels has been examined. Fifty patients with resectable pancreatic head cancer were examined regarding both the tissue and serum levels of DCP. The mean tissue DCP in the cancer tissue, non-cancer tissue, the serum levels in patients, and the serum levels in controls was 190.500 mAU/ml mg protein, 32.000 mAU/ml mg protein, and 46.000 mAU, and 10.000 mAU, respectively. The elevation of tissue and serum levels of DCP in pancreatic adenocarcinoma patients is a very useful marker for pancreatic adnocarcinoma and should be used without any other tumor marker (Tab. 2, Ref. 15).

RESUMO

To analyze the serum levels and prognostic significance of vascular endothelial growth factor (VEGF) family (VEGF-A, -C and -D) and their receptors (VEGFR-1 and -2) in patients with hepatocellular carcinoma. The serum levels of VEGF family members were measured in 56 control subjects and 68 patients with hepatocellular carcinoma using an enzyme-linked immunosorbent assay (ELISA). These measurements were correlated with clinic pathological features. The serum levels of VEGF-A and its receptor, VEGFR-1, were significantly higher in patients with hepatocellular carcinoma than in controls (p < 0.001). There was no significant difference in serum levels of VEGF-C and VEGFR-2 between patients and controls. VEGF-A levels were associated with advanced tumor stage and presence of metastases. VEGFR-1 was associated with metastases, advanced overall stage, tumor differentiation. VEGFR-2 levels were associated with poor tumor differentiation. Serum VEGF levels are significantly in the same cohort of patients with variable clinic pathological features and prognostic values. The measurement of VEGF-A and its VEGFR-1 levels in sera may reflect the development of tumor, metastasis and angiogenesis (Tab. 2, Ref. 20).

RESUMO

BACKGROUND AND AIMS: L-carnitine as an endogenous cofactor has a role in the regulation of energy flow between different oxidative sources. The purpose of this study is to investigate that the clinical and histopathologic effects of L-carnitine locally and systemically on secondary healing in wounds of full thickness defects. We also measured the effects of L-carnitine on wound tensile strength as mechanical. MATERIAL AND METHODS: sixty adult male Sprague-Dawley rats were divided into three groups randomly; group 1 (control group, n = 20), group 2 (local experimental group, n = 20), group 3 (systemic experimental group, n = 20). Group 1 was not given any pharmacologic agents. L-carnitine was administered locally in the group 2, and systemically in group 3 for a total of 14 days. The healing days of all groups were recorded. On the 7th, 10th,14th and 21st postoperative days, biopsy specimens, including tissue samples both from healing wound sites and sur-rounding healthy skin were evaluated for neovascularization, inflammation, the amount of collagen deposit, fibroblast migration and re-epithelization. Tensile strength was measured in the samples which completed healing on the 30th day. The results were evaluated by nonparametric Kruskall-Wallis test followed by Mann Whitney-U test. RESULTS: the mean clinical healing days were 18.25 days, 16.5 days, 15 days for the control group, local experimental and systemic group, respectively. The differences between groups were statistically significant (p < 0.005). Mean tensile strength values were 762.10 centinewton (cN), 801.69 cN and 786.13 cN for the control group, local experimental group and systemic experimental group, respectively. There were no statistically significant differences between groups (p > 0.05). There was no statistically significant difference in the histopathologic ex-amination on the 7th, 10th, 14th and 21st days in the neovascularization, inflammation and fibroblast migration. Collagen deposit was most prevalent in the systemic experimental group and was least in the control group. Complete wound closure rate was observed on the 7th day in the systemic administration group, on the 10th day in local administration group and on the 14th day in the control group. Re-epithelization thickness in the systemic carnitine group was more than the other groups. CONCLUSIONS: L-carnitine administered locally or systemically has positive effects on wound healing rate and tensile strength in rats.

RESUMO

The aim of this study was to analyze the serum levels and prognostic significance of vascular endothelial growth factor (VEGF)-A, -C, and -D, and their receptors, VEGFR-1 and -2 in inflammatory bowel disease (IBD). The serum levels of VEGF family members were measured in 80 control subjects and 200 patients with inflammatory bowel disease using an enzyme linked immunosorbent assay (ELISA). These measurements were evaluated with regard to the levels of inflammatory markers, such as C reactive protein (CRP) and serum amyloid A (SAA) and the clinical characteristics of patients, so that potential correlations could be recorded. A correlation between VEGF and their receptors serum levels is present in IBD patients. These new findings open the question on the potential role of VEGF and their receptors in IBD (Tab. 2, Ref. 9).

RESUMO

This study tested the hypothesis that individual counselling in the third trimester would increase postpartum contraceptive use to a greater extent than only providing an educational leaflet. A total of 180 third trimester pregnant women of mean age 28.3 years who were attending Marmara University Hospital for prenatal care were enrolled. One-third were randomly allocated to receive prenatal contraceptive counselling and the remaining two-thirds (control group) received an educational leaflet. Participants were followed-up at 6 - 9 months postpartum. The majority of subjects (91.5%) wanted to use contraception after delivery but 26.7% did not know which method to use. At follow-up, 79.6% of all women had begun a postpartum contraceptive regime and 68.7% were using a modern contraceptive method. Overall, there was no statistically significant difference in postpartum contraception use between the control and intervention groups in this study population. It is, therefore, concluded that prenatal counselling was not superior to educational leaflets for increasing the use of effective and modern postpartum contraception.

RESUMO

AIM: Osteoporotic vertebra and hip fractures are major causes of dysfunction, disability, mortality and impaired life quality in the ageing population. In the postmenopausal period, exercises prevent rapid bone loss and increase muscle strength, mobility and flexibility thereby decreasing the risk of falls and fractures. Yoga exercises, which have been an inseparable part of Eastern culture for hundreds of years, are now being used in the field of osteoporosis rehabilitation. Yoga has a positive effect on balance, posture, flexibility, and life quality resulting from its effects on balance, stretching, relaxation and strengthening. The aim of this study was to evaluate the effect of yoga exercises in postmenopausal osteoporotic women on balance and life quality and to compare the results with a classic osteoporosis exercise program. METHODS: Twenty-six postmenopausal osteoporotic women over 55 years of age were included in the study. A neuromuscular test battery and the QUALEFFO as a life quality index were used for the assessment of balance and life quality, respectively. RESULTS: The results showed that yoga education has a positive effect on pain, physical functions, social functions, general CONCLUSION: In conclusion, yoga appears to be an alternative physical activity for the rehabilitation of osteoporotic subjects.

RESUMO

Splenic artery aneurysms are the most common visceral artery aneurysms and are known for their potential for rupture. Pregnancy and portal hypertension have been known as major risk factors. With improved methods of diagnosis and minimally invasive therapy, management and outcome of SAA may change significantly. SAA may rupture at any age. When rupture of the aneurysm occurs, the mortality rate remains low if immediate resuscitation is performed and an aggressive surgical approach is taken. Conservation of the spleen might have been preferred.

RESUMO

Patient with hypertriglyceridemia history tends to develop a pancreatitis episode. Triglyceride levels > 1000 mg/dl may trigger this pathology. Amylase is not a good predictor for pancreatitis associated with hypertriglyceridemia. Because of the close relation between pancreas and splenic vein, pancreatitis is the most common etiologic factor in developing thrombosis or occlusion in splenic vein. The impairment or cessation of venous flow in splenic vein results in back pressure which is transmitted through short gastric and gastroepiploic veins and subsequently via the coronary vein into the portal system. Increased flow across the short gastric veins creates sinistral portal hypertension. Recurrent upper gastrointestinal hemorrhage is the last scene of this sequence in general, and may be unique sign. This case is extremely rare to understand all the cascade mechanism at once.

RESUMO

Osteoporosis and consequent fractures have become an important health problem all over the World. However, there are quite different fracture rates among different populations. In this study, our aim was to obtain the bone mineral density (BMD) values at calcaneus in a healthy Turkish population and compare them with Swedish population data. BMD was measured at the calcaneus using a dual X-ray and laser Calscan (Demetech AB, Stockholm, Sweden) bone densitometer. The total number of subjects was 951 consisting of 639 women and 312 men and age ranged from 15 to 79 yr. Mean BMD value for healthy young women (20-39 yr old) was 0.411+/-0.058 g/cm2 and for healthy young men was 0.504+/-0.068 g/cm2. BMD values tended to decrease with age in both genders. In comparison between the Turkish and Swedish population data, the Turkish population has about 1 standard deviation lower BMD values than the Swedish population in both genders, for all ages. Considering that Swedes have high fracture rates and Turks have the lowest fracture rates in Europe, the opposite difference in BMD values in the calcaneus seems interesting. Further research is needed to explain the difference in fracture rates among different populations.

RESUMO

AIM: The purpose of this study was to evaluate bone mineral density (BMD), bone parameters, complete blood count, erythrocyte sedimentation rate, electrolyte values, back pain, compression fracture and quadriceps muscle strength in mild and moderate renal insufficiency patients. METHODS: Thirty-six female, 3 male, patients with the diagnosis of osteoporosis in addition to mild or moderate chronic renal insufficiency who were followed in Istanbul University, Cerrahpasa Faculty of Medicine, Physical Therapy and Rehabilitation Department, Osteoporosis and Nephrology Outpatient Clinics between March 2003 and March 2004, were included in the study. In the control group there were 17 female, 5 male patients with osteoporosis but without renal insufficiency. The inclusion criteria were to have osteoporosis, be aged between 40-70 with a creatinine clearance between 30-70 mL/min in the case group, >70 mL/min in the control group. The patients whose creatinine clearance was <30 mL/min, and whose BMD was normal or osteopenic even though creatinine clearance was >30 mL/min were excluded from the study. RESULTS: There was no significant difference with respect to back pain, compression fracture and quadriceps muscle strength between the 2 groups. The mean value of neck BMD, T and Z score were significantly lower in the case group (P<0.05). CONCLUSIONS: As a conclusion, PTH related bone disease had an important effect on BMD, although, the risk factors for osteoporosis were equally important. In various researches, the relationship between BMD values and history of fracture in renal osteodystrophy patients could not be shown. In our study, the history of prior fracture or fracture in the family were important risk factors for osteoporosis. Renal osteodystrophy patients had low BMD values in mild and moderate stages of the disease. Prior fracture as well as osteoporotic fractures in the family should be part of a comprehensive evaluation of the patient.

RESUMO

This study was performed to evaluate breast muscle development in chicken genotypes divergently selected for muscularity. In the first experiment, 2 commercial broiler lines (a high breast yield, HBY, and a normal breast yield broiler strain-cross, NBY) and a Leghorn line were grown up to 35 d to evaluate BW, breast weight, and breast yield. At 7 and 21 d of age, pectoralis muscle was used to estimate myofiber density (MFD, number of myofibers per mm2) and total apparent myofiber number (MFN). In the second experiment, the ontogeny of myostatin was determined from broiler- and Leghorn-type chick embryos, at embryonic days 1 to 20 (E1 to E20), using reverse transcription (RT)-PCR. As expected, the Leghorn line had lower BW, breast weight, and breast yield than broiler lines. The HBY line showed higher breast yield at all ages evaluated, but lower BW at 21 and 35 d than the NBY line. The Leghorn line had 45% higher MFD than broilers, which indicates an increased cross-sectional area of the myofibers in broiler lines. No MFD difference was observed between the broiler strains (P > 0.05). The myofiber number of broilers was more than twice that of Leghorns and HBY had 10% higher MFN than the NBY line. Myofiber number was correlated to BW (r = 0.58), breast weight (r = 0.58), and breast yield (r = 0.69). Conversely, MFD showed negative correlation with BW, breast weight, and breast yield (r = -0.85, -0.83, and -0.88, respectively). No effect of genotype or interaction between genotype and embryonic age was observed for myostatin expression. This study showed that broilers have higher MFN in the breast muscles than Leghorn-type chickens, and that high breast yield of broiler strains may be due to increased MFN. Higher muscularity of broilers, as compared with Leghorns, was not attributed to lower expression of myostatin during embryonic development.
